SPECIFICATION forming part of Letters Patent No. 606,435, dated J' une28,1898.

` Application filed June 8, 1897. Serial No. 639,919. (No model.)

.To all whom it may concern.-

Be it known that I, J QHN F. WILI.IAMS,-` a citizen of the UnitedStates,residing at Kansas City, in the county of Wyandotte, in the State ofKansas, have invented certain new and useful Improvements inGasGenerating I p Gas-Fixtures, of which the following is a full,

clear, and exact description, reference being had to the accompanyingdrawings, which are made a part of this specification.

lWIy invention relates to improvements in gas-generating gas-iixtures inwhich, in passage through the fixture, the gas is generated from liquidhydrocarbons, is mixed with a suitable quantity of air, and delivered tothe ignition-tube Without the interposition of any of the usualforms ofgenerators or burners; and my invention consists in certain features ofnovelty hereinafter described, and pointed out in the claims.

Figure I represents a gas-fixture embodying my invention. -Fig.lIIrepresents a longitudinal cross-section of the generating-tube and itscooperative parts. Fig. III represents a cross-section of.theignition-tube. Fig. IV representsa modified form of tip for thegeneratingtube. Fig. V represents a view in cross-section of apreferable means of l forming the tapering passage in thevaporizingtube; and Figs. VI, VII, and VIII, views illustratingmodiiications and variations hereinafter referred to. y

Similar numerals refer to similar parts throughout the several views.

1, 2, 3, and 4 represent the tubing or pipes forming the fixture,connected by YtheTs 5, G, 7, and 8.

9 represents a tube or pipe passing through the vessel 10, containing asupply of liquid hydrocarbon and connected with the fixture by the T 7.Vithin said vessel said tube is provided with one or more openingscovered by the gauze screen 11 for Aadmitting the liquid to the tube andthence tothe fixture, the screen serving to prevent the admission ofextraneous matter, the sides of said vessel being partly broken away toshow the same. Said tube, extending above said vessel, may be attachedtoaI Wall or ceiling-hanger or other convenient support.

The tubes 9 and 4 constitute the supplytube.

12 represents the vaporiZing-tube, connect-- ed With the supply-tube lthrough the T 6 and provided with the shutoff valve 13. It Will beobserved, as shown in Fig. II, that the passage through said tubediminishes from the heavier or unvaporized particles and pre ventclogging of said opening thereby. The

heavy or unvaporized particles naturally tend to adhere to the innerWalls of the tip 14 and to travel therealong toward thedischargeopening, but the collar 17 arrests them and prevents theirdischarge. 18 represents a sleeve surrounding said tip provided With theopenings 19, arranged to slide on the tube 20,

connected with the T 5 and adjustable theref on by the set-screw 2l, thepurpose of said sleeve being to regulate the air-supply admitted to mixWith the vapor issuing from the tip. In operation the tube or sleeve 18should not come into direct contact With the tip, for should suchcontact occur theheat would be drawn from the tip and the tip therebycooled.

The pipe 1 forms the mixing or diffusing tube, connecting through the T8 with the tube 22, leading to the burner 22A.

23 represents a chimney-holder formed With the sleeve 24, arranged toslide over the tube 22 and rest upon the shoulder 25 thereon. 26represents a cup formed on said sleeve. represents a sleeve arranged tobe fitted Within said cup and-provided with the gauze Screen 2S, formingthe burner.

29 represents the chimney,the arrangements of the parts being such thatthe vaporizingn tube extends across the line of the chimney a shortdistance above the same.

30 represents a chimney-support.

31 representsan envelop or mantle of refractory incandescing materialarranged to surround the flame and form an incandescent mantle aroundthe same. I 2 represents a support for said mantle. 38 represents asetscrew for adjusting the Slle.

yIn Fig. IV is shown a :modification 'of the coupling and tip shown inFig. II, which I preferably use when a fixture Withmore than one lightis desired. In such case I provide the coupling 15 with the head 34,having `the IOO openin gs 35 for the passage of the vapor from thevaporizing-tube to the tip and having the needle point 36 set thereinand extending through the openingl in the tip, the arrangement beingsuch that by adjustment of the tip upon the coupling the fiow of vaporthroughy a tube having a straight passage by placingv therein a rod 37,filed or dressed to'form such tapering passage, as shown. The rod issimply held in place by frictional contact and may be readily Withdrawnwhen it is desired or may become necessary to clean it.

When a fixture with more than one light is desired, arms 38 (shown indotted lines in l Fig. I) may be supplied, provided With-burnerssimilar'to the one shown, all said burners being supplied from themixing-tube 1.

In operation my improved apparatus is exceedingly simple. rlhe liquidhydrocarbon passing from the vessel 10 through the tubes 9 and 4 to thevaporizing-tube 12 is there Vaporized by the heat from the flameconcenproXimity under said tube. The tube 9 being larger than the tube 4and the tube 4 larger than the vaporizing-tube and the passage in thevaporizing-tube decreasing in size from inlet to outlet, it is apparentthat by reason of the constant decrease in size of the passage from theinlet of the liquid into the pipe 9 to the exit of the vapor from thevaporizing-tube any back press-ure in the tubes generated during theprocess of vaporzatiou meets the least possible frictional resistance,and the exit of the vapor will be steady and cannot puff and blow andcause uneven pressure. In other Words, by the arrangement andconstruction of the passages as shown, but leaving them otherwise clearof any packing or filling material, the particles or molecules of theliquid as they expand or are converted into gas ymay exert theirpressure in a rearward direction and not tend, as in the usualv burners,to force the gas out through the tip under uneven impulses. The vaporpassing from the vaporizing-tube passes through t'he opening in the tip14 into the air-supply chamber formed by the sleeve 1S, the expansion ofthe vapor in the coupling tending further to promote a continuous andsteady fiow of the vapor from the tip, the collar 17 'Within the tippreventing foreign matter from reaehingthe opening and clogging thesame. By adjustment of said sleeve 18 0n the tube 2O the amount of airadmitted is regulated and controlled, the air entering through theholes19 and at the space between the sleeve and coupling, as shown bythe a1'- rows in Fig. II. passing through the tubes becomes thoroughlymixed in passage and passes to the Thence the air and vapor burnerthrough the tube 22, andY by surround- 'ing the flame with theincandescing mantle I obtain by this simple and cheap apparatus a verybrilliant and powerful light.

Among .the advantages gained by my improved apparatus may be mentionedthe simplicity of its construction, a constant and even pressure fromthe source of supply to and through the vaporizing-tube, a constant andeven' heat upon the vaporizing-tube resulting in constant and evenvaporization, the perfect control ofthe air-supply, and the constant andperfect mixing and diffusionof the air and vapor before reaching thepoint of ignitiomand there being few parts and all simple and easilyaccessible it is little liable Y to get out of order, and any failure-ofthe parts can be easily remedied.

I have preferably arranged the vessel and tube in the relation shown inFig. I; but it is apparent that the vessel may be put on the side of thepipe, as shown in Fig. VI, or, as i shown in Fig.VIII,the vessel maybesupported and arranged in any convenient manner and have a pipe 40 runalong the ceiling-or other `place and one or more fixtures connected tov the same Without departing from the princi- Y pal construction shown.

trated through the chimney arranged in close The fixture can be variedin construction in many Ways-as, for instance, as shown in Fig.

VII, I could leave out pipes land 3 and putin an L at 8in place of theT, letting the tube y 12 pass over and back across the chimney anddischarge the generated gas and air -into pipe 2, making amixing-chamber of Yit the same as with pipe 1. So, too, instead ofpassing the vaporizing-pipe 12 directly over the chimney I may place itlower down and pass it around the chimney, such construction being shownin the burner upon the left of Fig. VIII.
